시스템 엔지니어가 바라보는 시맨틱웹과 빅데이터 기술

  1. 1. 1 System Engineer Viewpoint to Semantic Web and Big Data Technology 2012.11.19 Youngsung Son
  2. 2. Semantic Web2  Machine Understandable Information about Web resources or other things – Tim Berners-Lee, W3C, 1997  Web (HTML, HTTP, URI) – How to use it for machine as data  Semantic Web Elements – URI, XML, RDF, OWL – RDFS, SPARQL, …
  3. 3. Semantic Web Layer Cake3
  4. 4. Semantic Web Applications4  Intelligent Search – Naver Semantic Movie Search – Google Knowledge Graph – BBC Program Search – …  Knowledge Management – Digital Library – Hospital – eHealth, Medicine, Disease, … –…
  5. 5. Societal Trends5  Data Explosion – Internet, Web, email, … – SmartMedia, SNS, image, video, … – Database by Corporation & Government – The Internet of Things (IoT)  Scale of Things to Come – In 2002, 22 Exabyte (1018) – In 2006, 161 EB – In 2010, 988 EB (almost 1 ZB) – In 2011, 1.8 zettabytes (1.8 trillion gigabytes)
  6. 6. If System Engineer meet Semantic Web?6 Artificial Assistance ICT system can change the world better! Wireless, Wearable Computer Google Self-Driving Car Power Grid Management
  7. 7. The Internet of Things7  Everything can connect to Internet 7
  8. 8. 8
  9. 9. 9
  10. 10. Components of IoT10  Contextual reasoning – How to improve application capacity to sense, understand, and reason about complex and dynamic data and situation?  Knowledge representations and interaction techniques – How to augment cognitive reasoning with perceptual reasoning through visual representations and interactions?  Data Representations and transformations – How to transform data into a representation that is appropriate to the reasoning task and effectively patch the important content?  Production, presentation, and dissemination – How to convey analytical results in meaningful ways to various audiences?
  11. 11. Requirements of System Engineer11  Portability  Interoperability  Scalability  Productivity
  12. 12. XML is a good data format. But …12 XML??? Something Wrong!!!
  13. 13. Interoperability13 Transformable Technology is required!!!
  14. 14. Sensor Discovery on Linked Data14 http://www.w3.org/2005/Incubator/ssn/wiki/Sensor_Discovery_on_Linked_Data
  15. 15. Extending the Web to objects15 15
  16. 16. Contexualization of Things16 Things Context
  17. 17. IoT Entity Model17 Frieder Ganz, Payam Barnaghi, Francois Carrez and Klaus Moessner, "Context-aware Management for Sensor Networks", in the Fifth International Conference on COMmunication System softWAre and middlewaRE (COMSWARE11), July 2011.
  18. 18. IoT Platform for Real-World and Digital18 Objects Suparna De, Tarek Elsaleh, Payam Barnaghi , Stefan Meissner, "An Internet of Things Platform for Real-World and Digital Objects", Journal of Scalable Computing: Practice and Experience, vol 13, no.1, 2012.
